ATTORNEY United States Patent MOP HEAD COMPRISING TWO PARALLEL MEMBERSHenning R. Larson, Worcester, Mass.

Application January 5, 1951, Serial No. 204,535

1 Claim. (Cl. 15229) This invention relates to new and improved mopconstructions and the principal object of the invention resides in theprovision of a double ended mop including a pair of mop holders or headsheld in spaced relation by a bridge member on which the mop yarns areabsent, said bridge member providing a new and improved handleconnection for the mop heads.

A further object of the invention resides in the provision of a doubleended mop as above described for more etficient dust removal either bymanual shaking or by actuation in the machine according to my Patent No.2,230,356, dated February 4, 1941.

A further object of this invention resides in a new and improved mophead and holding means for the mop yarns in combination with a new andimproved mop handle connection.

Other objects and advantages of the invention will appear hereinafter.

Reference is to be had to the accompanying drawings in which Fig. 1 is aperspective view of the new mop, parts being in section;

Fig. 2 is a longitudinal sectional view through the mop handleconnection;

Fig. 3 is a section on line 3-3 of Fig. 2; and

Fig. 4 is a section On line 4-4 of Fig. 2.

The present invention comprises a pair of mop heads each of whichconsists of a rectangular enclosure generally indicated at and 12. Theseenclosures may be made of channel members as clearly shown in Fig. 3,each of which is provided with an open bottom at 14 and side members 16.A rubber bumper member 17 may be secured to the latter. Fasteners 18extend from one arm 16 to the other in each enclosure, beneath rods 20over which the mop yarns 22 are looped and closely engaged by means ofwire twists or the like securing the yarns to the rods 20. In Figs. 2and 3, these yarns are shown as not being full in order to illustratethe invention more clearly. Actually the mop yarns are very full asindicated in Fig. 1.

The mop heads 10 and 12 are connected by a bridge member 24, which mayalso comprise a channel member having an open side 26 and flattened ends27 for secure- Patented Nov. 29, 1955 ment to the heads 10 and 12 as bywelding or any other desired means. The bridge 24 holds the mop heads 10and 12 in parallel spaced condition and it will be clear that when thebridge part 24 is rapidly oscillated about an axis extendingtransversely thereof in the direction of the handle receiving sleeve 28,the yarns will receive the maximum agitating action possible and thuswill be cleaned more easily and quickly, than would be the case were themop heads so arranged as to extend across the center in the position ofthe bridge 24. This action may be done manually or in the machinedisclosed in the above identified patent.

The bridge 24 is provided with a spacer 30 through which extend a pairof bolts, rivets or the like 32 engaging projecting arms 34 and 36 of asquare elongated tubular member 38. The latter contains a square stud 40held thereto by a square washer 42 overlapping the side edges 44 of thesquare tubular member 38 and secured to the stud 40 by a fastener 46.

The stud 40 has secured fixedly thereto and longitudinally thereof ashaft 48 which may be mounted in bearings 50 in a sleeve 52 and insleeve 28, there being a gap as at 54 between the sleeves. This gapreceives a gear 56 secured to the shaft 48. The gap 54 is bridged by amember 58 which secures the two sleeves 28 and 52 together.

The eflect of this construction is that the shaft 48 is rotatable in thesleeves.

A handle 60 may be secured in any desired manner as by a pin 62 tosleeve 28. Handle 60 is used in the usual manner to manipulate the mopfor its usual purposes.

Having thus described my invention and the advantages thereof, I do notwish to be limited to the details herein disclosed otherwise than as setforth in the claim, but what I claim is:

A mop head comprising a pair of spaced elongated parallel mop heads infixed relation to each other, a transverse channel shaped bridgeconnecting the heads and securing and spacing the same in said fixedrelation, each mop head comprising a separate channel member each havingclosed side walls and one open side, said open sides facing in the samedirection, a rod passing through each channel, mop filaments looped overthe rods and held in position by the channel walls, and extending out ofthe channels through the open sides thereof.
